Cybersecurity by executive order

This report explores the details of the Obama Administration\u27s executive order on cybersecurity, breaking down the challenges, criticisms, and successes of the effort to date, before offering clear lessons from the US experience that can be applied to the Australian context. Summary: On 12 February 2014 the United States National Institute of Standards & Technology (NIST) released the Framework for Improving Critical Infrastructure Cybersecurity, the flagship accomplishment of the Obama Administration’s 2013 cybersecurity Executive Order. Just weeks before the White House announced its executive order, the then Australian Prime Minister Julia Gillard made an equally exciting declaration introducing the Australian Cyber Security Centre (ACSC). One year on, the contrast between the two efforts is stark. The United States and Australia share a common interests in developing a robust partnership between the government and private sector to develop whole-of-system cybersecurity. To move beyond political optics, the ACSC must embrace existing best practices, commit to meaningful public-private partnerships, and set a pragmatic strategy moving forward. The Obama Administration’s efforts, while far from perfect, offer critical lessons that the Australian government can adopt and adapt to ensure that the ACSC is a successful endeavour and critical infrastructure cybersecurity is improved. This Strategic Insight report explores the details of the executive order, breaking down the challenges, criticisms, and successes of the effort to date, before offering clear lessons from the US experience that can be applied to the Australian context

Retrospective study of the correlation of serum potassium concentrations and the findings of heart auscultation in calves with neonatal diarrhea

A retrospective study was conducted of clinical records of calves with neonatal diarrhea up to the age of 14 days concerning certain aspects of blood potassium concentration and heart rate and rhythm. No correlation could be found between heart rates and serum potassium concentrations. Bradycardia was no indicator of hyperkalemia, nor could hyperkalemia be ruled out in animals with tachycardia. Cardiac arrhythmias were not associated with pronounced kyperkalemia, and did not indicate a poor prognosis. It was concluded that, at least in clinical cases of neonatal calf diarrhea, heart rate and rhythm are subject to complex influences and yield no information on the actual serum potassium concentration in a particular animal

Lexicographic shellability, matroids and pure order ideals

In 1977 Stanley conjectured that the $h$-vector of a matroid independence complex is a pure $O$-sequence. In this paper we use lexicographic shellability for matroids to motivate a combinatorial strengthening of Stanley's conjecture. This suggests that a pure $O$-sequence can be constructed from combinatorial data arising from the shelling. We then prove that our conjecture holds for matroids of rank at most four, settling the rank four case of Stanley's conjecture. In general, we prove that if our conjecture holds for all rank $d$ matroids on at most $2d$ elements, then it holds for all matroids

Laboratory Rearing of Phalangium Opilio (Arachnida: Opiliones)

While a good deal of work has been reported on the natural history and ecology of the opiliones in Europe and England (Bristowe, 1949; Sankey, 1949; Todd, 1949; Phillipson, 1959; Savory, 1964; Juberthie, 1965), this important group has received little attention in North America. Bishop (1949) published a concise synopsis of reactions and general habits of the opiliones of New York and, in a Ph. D. dissertation, Edgar (1960) described the biology of the order in Michigan. Current studies at Michigan State University on the effects of insecticides on non-target organisms have revealed an acute lack of biological information on the group, and before the effects of insecticides could be determined, life histories of the opiliones had to be clarified. Consequently, in 1966 a study of the ecology and rearing requirements of selected Michigan species was initiated. The present paper describes a new incubation technique for opilione eggs that shows promise of facilitating laboratory rearing of this group
